Best ResponseYou've already chosen the best response.1First, what is the biggest factor of the coefficients, 2 , 22 , 60 ?

Best ResponseYou've already chosen the best response.1no, you can not take a multiple of 60 out of 2 or 22

Best ResponseYou've already chosen the best response.12 is the largest thing that can divide evenly into all three of those

Best ResponseYou've already chosen the best response.1so you can say \[2x^4+22x^3+60x^2 = 2*(x^4+11x^3+30x^2)\]

Best ResponseYou've already chosen the best response.1now, since you have just x variables, the greatest one you can pull out of all three will be the smallest power, only if every term has x, like here

Best ResponseYou've already chosen the best response.1\[2*(x^4+11x^3+30x^2) = 2x^2*(x^2+11x+30)\]

Best ResponseYou've already chosen the best response.1Really are just multiplying the thing by x^2 / x^2 or 1, and keeping the numerator out front, and dividing everything by the x^2

Best ResponseYou've already chosen the best response.1Now since 2x^2 is not an answer, look further, factor the remaining ( ) part
